When I start MyCroft on my Raspberry Pi 4 running Raspbian it seems to start alright but it can’t hear me, so I tried running it with debug and audiotest ammeneded it the end, but it spits out an error.

I tried installing xxhash (pip install xxhash) but that hasn’t remedied the problem.

Any help and/or suggestions highly appreciated.

Before installing, start the virtual env (source ~/mycroft-core/.venv/bin/activate && pip install xxhash)?

Okay, thank you for answering! I’ve tried that but it hasn’t seemed to have worked.

Here’s everything I tried and the responses I got back:

https://paste.ubuntu.com/p/v8vmbNpTGM/

With the venv active, can you run python3 and try “import xxhash”?

Thank you but it still doesn’t seem to be working.

Here’s what I tried and what happened:
https://paste.ubuntu.com/p/wTqf6HwB6T/

I also tried a couple of things suggested to me on Reddit.

Something’s wrong with your installed xxhash, it seems. Try uninstalling it and reinstalling new?

within venv or just normal sudo?

within the ~/.venv , where you land in after login - you shouldn’t need sudo - the py env is in user home dir , right ?

I tried uninstalling and reinstalling xxhash and here’s the outputs:

https://paste.ubuntu.com/p/bJyJ8G9Y6Y/

I followed the Linux guide and to active the .venv I use (source ~/mycroft-core/.venv/bin/activate) so yeah.

Could you please run the following commands and paste us the ouput?

$ source ~/mycroft-core/.venv/bin/activate
$ whereis python

It should return a list of paths and one of them should be /home/pi/mycroft-core/.venv/bin/python

If it’s the case then, try to run this:

$ /home/pi/mycroft-core/.venv/bin/python

Hi! Thank you for your response! Below you’ll find the outputs to everything you asked!

Sorry about the whereis typo… Could you please do the same with pip ?

$ source /home/pi/mycroft-core/.venv/bin/activate
$ whereis pip

You should have a line like this /home/pi/mycroft-core/.venv/bin/pip , then try this:

$ /home/pi/mycroft-core/.venv/bin/pip install xxhash
$ /home/pi/mycroft-core/.venv/bin/python

Hahaha it’s okay, I at least worked out how to fix that!

This is insane, I never saw something like this… Try this:

This is truly a mixture of pain and humour at this point, but here you go:

I’m starting to run out of ideas… Try this:

$ /home/pi/mycroft-core/.venv/bin/pip install --force-reinstall xxhash

Okay WOW! That might have worked!

I’ll comment again if anything fails but it’s downloading skills right now!

Damn… Not an easy one!

Thank you sooooo much!
It’s 1am where I am so I’ll probably try and set it all up and pair it in the morning!

I’m genuinely so grateful! Thank you! :smiley:

You are very welcome, please edit you post with [solved]. :+1:
